Maintaining optimal indoor air quality and efficient HVAC systems in office buildings is critical for energy performance and comfort. At Building Ventilation Solutions Ltd, we specialise in Air Handling Unit (AHU) refurbishment, extract fan upgrades, duct replacement and comprehensive ventilation services tailored specifically for office environments across the UK. With over 40 years’ experience in delivering cost‑effective, high‑impact HVAC projects, we help building owners and facilities managers upgrade ageing systems and extend the life of their critical ventilation assets.
Why AHU Refurbishment Matters for Office Blocks
Office ventilation systems handle large volumes of fresh air to keep staff comfortable and productive all year round. Over time, components like fans, coils and dampers can wear, causing reduced airflow that can lead to higher energy usage and poorer indoor air quality. Our AHU refurbishment solutions breathe new life into existing systems by:
- Replacing outdated components with modern, energy efficient fans and controls.
- Upgrading coils and filters to improve performance and air quality.
- Repairing and reinforcing structural elements of the unit to extend service life.
By refurbishing rather than replacing AHUs, clients often achieve substantial savings, typically around 40 % less than the cost of new units, and minimise disruption to daily operations.
Below are some examples of previous office blocks that we’ve helpd:
Case Study: Pembroke Court Offices – AHU Refurbishment
At Pembroke Court, our team delivered a comprehensive AHU refurbishment as part of a modernisation drive following the building’s front‑of‑house upgrades. The project included:
- Removal of old belt‑driven supply fans and installation of efficient EC fan arrays.
- Structural casing repairs and rust treatment.
- Full replacement of heating, cooling and frost coils with updated reverse‑cycle coils.
- Installation of new electric heater batteries and improved filter bulkheads.
By upgrading these major components, we improved airflow, reliability and occupant comfort, setting a new standard for HVAC performance in this office block.
This project illustrates how AHU upgrades transform otherwise ageing systems into efficient, reliable plant that supports building performance and sustainability goals.

Case Study: Gresham Street Office – Strategic HVAC Upgrades
Our 10 Gresham Street project is another standout example of effective AHU refurbishment in a busy commercial office environment. On this project we assessed existing systems and implemented targeted upgrades that revitalised the building’s ventilation assets.
By adopting modern technologies and proven refurbishment practices, we improved energy efficiency and extended the service life of key plant. This case study highlights our ability to tailor solutions to the unique challenges of central London office blocks, including access constraints and phased works planning to minimise operational impact.

Case Study: Burlington Street Office – Extract Fan & Duct Replacement
Office ventilation performance isn’t just about AHUs, the extract fans and ductwork that distribute and remove air throughout a building are equally important. On the Burlington Street Office project, Building Ventilation Solutions undertook a significant extract fan replacement and duct refurbishment scope to ensure optimal airflow throughout the block.
This included:
- Installing upgraded extract fan units to improve airflow and reduce noise.
- Replacing or refurbishing ductwork to prevent leaks, blockages and inefficiencies.
- Ensuring full coordination with existing HVAC plant and controls.
The result was improved ventilation performance and indoor air quality, demonstrating our expertise beyond AHUs to deliver all‑round HVAC excellence.
